DBX 223XL
Let’s take a look at the construction features of the dbx® 223XL. As you turn the controls you
will notice that these units are extremely well built. The controls exude great precision, and the
feel is a solid "click". Also, when you open the box, you won’t find the external power supply
that accompanies most processors in this price range. That’s because we know how difficult
external power supplies can be to work with and even though it costs a little more, we put the
high quality power supply right in the unit.
All the inputs and outputs are balanced XLRs that are screwed directly to the chassis. This
connection of the jacks to the chassis insures that even if someone stomps on a cable plugged
into the unit, it’s not going to tear up the circuit board inside. All dbx crossovers feature
Linkwitz-Riley 24dB per octave filters, the professional standard. But then again, what did you
expect?
Via a switch on the back panel, you first select whether you’re operating your system in stereo
2-way or mono 3-way. Then you also set, on the back panel, whether or not you want to mono
sum the LF (subwoofer) out. (Most systems that use a subwoofer are mono subbed to take
advantage of amplifier power and because low frequencies are non-directional.) Back panel
switches allow you to select the range of the crossover frequencies individually for both
channels. The crossover frequency controls have a green LED that indicates when the x10
switch on the back panel is activated (we wouldn’t make you check the switch position on the
back every time you wonder where it’s set). All these switches are on the back panel because it
could be disastrous if you were to change them mid-program. On the front panel you’ll notice
there are LEDs that indicate whether the unit is in mono or stereo mode. Each channel has an
input gain control for proper level setting. There’s a recessed 40 Hz low cut (HPF) on each
channel to remove unwanted low frequencies. Both the low and high outputs on each channel
have a gain control ranging from -infinity to +6 dB to allow muting of individual outputs and for
level matching. Also, these outputs each have phase reverse switches that will help get you out
of a bind without having to reconfigure your system. These phase reverse switches may be
internally reconfigured as mute switches.
You’ll get great performance, all the features you’d expect from a professional product and the
knowledge that you’re buying a processor from the people that have been producing the worlds
finest processors for over 25 years. The technology that made us famous brings you a dbx
crossover that has been tested to the highest professional standards at a price that’s just too

-
Filter type: Linkwitz-Riley, 24 dB/octave, state-variable
FUNCTION SWITCHES
- Front Panel (Low Cut): Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one
switch per channel
- Phase Invert: Inverts the phase at the output, one switch per output
- Rear Panel: x1 / x10: Multiplies the low-high(mono: low/mid and high/mid) crossover
frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel
- Mode: Selects stereo 2-way or mono 3-way operation and disables all LEDs for controls
that are non-functional in the selected mode
- LF sum: Selects normal (stereo) or mono-summed low frequency operation and disables
Ch 2’s low output phase invert LED to indicate that this output is not operational in the LF sum
mode
